Individuals who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being eliminated from one's system, which is frequently uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as necessary. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services often include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as necessary to make the detox process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can provide detox services, the person will have detoxification staff at their disposal around the clock to make certain that any issues are fixed as rapidly and safely as possible.
